The Siemens 3RG4031-6AD00 is an inductive proximity sensor from the SIMATIC PXI340 family, sensing up to 15 mm with a 10…65 VDC supply. Output is PNP, configurable as NO or NC, switching at up to 100 Hz and sinking max 200 mA. IP67 rated, it operates from -25 to 85 °C.
Housing is 40 x 40 x 120 mm, screw-terminal connection accepts standard wires. The PNP output can be wired for either NO or NC by selecting the correct pin — both are available in the same sensor, reducing the need for separate models. IP67 allows washdown environments, but verify the cable gland and mating connector integrity if used in a wet area.
